Speed Pick-up
SU63
The Validyne SU63 is an AC inductive speed pick-up used for RPM measurement on high-speed rotating equipment. The SU63 is a tightly-wound coil with a laminated core that can be conveniently mounted on rotating equipment so that the magnetic field of a magnetized nut or part passes through the coil windings. The moving magnetic field produces a voltage within the coil proportional to its rate of change and the strength of the permanent magnetized part. The frequency of this inductive voltage spike is fed into an oscilloscope or counter to determine RPM.

Computer-Based Instruments
GT210PCI
with the GT210PCI you can determine any frequency to 0.01 part per million (eight digits) in just 1 mS, and resolve each time measurement to 8pS. Couple that with 2300 measurements per second, one of the fastest rates available and you can acquire more data in a single second than a typical GPIB counter can in one minute! Faster measurements and higher resolution, along with built-in statistics functions give you a more thorough analysis of your signal. Standard deviation, peak to peak jitter, or a graph of the measurements are available at the push of a button.
